Apparatus and method for large area hermetic encapsulation of one or more organic light emitting diodes (OLEDs)

摘要

Apparatus and method for hermetically encapsulating one or more optoelectronic device, such as a light emitting device or a photovoltaic device. The apparatus comprises a base and a carriage movable along the base. The carriage comprises a roller. The apparatus further comprises a vacuum platen coupled with the base and a tensioner coupled with the base. The tensioner comprises a support member that projects orthogonally above a plane of the vacuum platen.

1. A method, comprising:
applying force from a roller to two sheets of encapsulating material(s), a first sheet tensioned to be substantially flat and a second sheet positioned at a predetermined angle relative to the first sheet; and moving the roller to hermetically encapsulate an optoelectronic device between the first sheet and the second sheet; the method further comprising: heating a platen, the platen having a flat surface with one or more holes therein; and moving the platen from a first position away from the first sheet of encapsulating material to a second position proximate the first sheet of encapsulating material.
